WARNING
When using the [RAIN] function, never set the
suppression level too high canceling out all image noises
from the rain or snow at the close range.
Detection of not only echoes from the rain or snow but
also targets such as other ships or dangerous objects will
become inhibited.
When using the [RAIN] function, make sure to choose the
most appropriate image noise suppression level.
A malfunction may occur if the power in the ship is
instantaneously interrupted during operation of the radar.
In this case, the power should be turned on again.
When using the [SEA] function, never set the
suppression level too high canceling out all image noises
from the sea surface at close range.
Detection of not only echoes from waves but also targets
such as other ships or dangerous objects will become
inhibited.
When using the [SEA] function, make sure to choose the
most appropriate image noise suppression level.
- vii -
Turn off the main power source before replacing parts.
Otherwise, an electric shock or trouble may be caused.
Before replacing the magnetron, turn off the main power
source and wait for 5 minutes or more until the high
voltage circuits are discharged.
Otherwise, an electric shock may be caused.
Take off your wrist watch when bringing your hands close
to the magnetron.
Otherwise, your watch may be damaged because the
magnetron is a strong magnet.
Two or more persons shall replace the liquid crystal
monitor.
If only one person does this work, he may drop the LCD,
resulting in injury.
Even after the main power source is turned off, some
high voltages remain for a while.
Do not contact the inverter circuit in the LCD with bare
hands. Otherwise, an electric shock may be caused.
The accuracy from the vectors are depending on the
accuracy from the (D)GPS sensors.
With longer vectors, the accuracy will be lower.
The vectors are calculated with the situation at that time.
When there will be some changed influence from wind,
water current etc, are not shown before the vessel is
influenced by this.
CAUTION
Do not put watches, clocks, or magnetic cards close to
the modulator unit since this unit holds magnetrons
having strong magnetic force. Failure or data
destruction of the above devices may result.

◆◆◆PRECAUTIONS BEFORE OPERATION◆◆◆
Cautions for high voltage
High voltages from hundreds volts to tens of thousands volts are to be applied to the electronic
equipment such radio and radar devices. You do not face any danger during normal operation,
but sufficient cares are required for maintenance, inspection and adjustment of their internal
components. (Maintenance, check-up and adjustment of the inside of the equipment are prohibited
except by maintenance specialists.)
High voltages of tens of thousands volts are so dangerous as to bring an instantaneous death from
electric shock, but even voltages of hundred volts may sometimes lead to a death from electric
shock. To prevent such an accident, make it a rule to turn off the power switch, discharge
capacitors with a wire surely earthed on an end make sure that internal parts are no longer charged
before you touch any parts inside these devices. At the time, wearing dry cotton gloves ensures
you further to prevent such danger. It is also a necessary caution to put one of your hands in the
pocket and not to use your both hands at the same time.
It is also important to select a stable foothold always to prevent additional injuries once you were
shocked by electricity. If you were injured from electric shock, disinfect the burn sufficiently
and get it taken care of promptly.
What to do in case of electric shock
When finding a victim of electric shock, turn off the power source and earth the circuit
immediately.
If it is impossible to turn off the circuit, move the victim away promptly using insulators such as
dry wood plate and cloth without touching the victim directly.
In case of electric shock, breathing may stop suddenly if current flows to the respiration center in
the brain. If the shock is not so strong, artificial respiration may recover breathing. When
shocked by electricity, the victim will come to look very bad with weak pulse or without beating,
resulting in unconsciousness and rigidity. In this case, it is necessary to perform an emergency
measure immediately.
- ix -
◆◆◆FIRST-AID TREATMENTS◆◆◆
First-aid treatments
As far as the victim of electric shock is not in dangerous condition, do not move him and practice
artificial respiration on him immediately. Once started, it should be continued rhythmically.
(1) Do not touch the victim confusedly as a result of the accident, but the rescuer may also get an
electric shock.
(2) Turn off the power source calmly and move the victim away quietly from the electric line.
(3) Call a physician or ambulance immediately or ask someone to call a doctor.
(4) Lay the victim on this back and loosen his necktie, clothes, belt, etc.
(5) a. Examine the victims pulse.
b. Examine his heartbeat bringing your ear close to his heart.
c. Examine his breathing bringing the back of your hand or your face close to his face.
d. Check the size of the pupils of his eyes.
(6) Open the victim’s mouth and take out artificial teeth, cigarette or chewing gum if any.
Keep his mouth open, stretch his tongue and insert a towel or the like in his mouth to prevent
the tongue from suffocating. (If it is hard to open his mouth due to set teeth, open it with a
screwdriver and insert a towel in this mouth.)
(7) Then, wipe his mouth so that foaming mucus does not accumulate inside.
- x -
When pulse is beating but breathing has stopped
(Mouth-to-mouth respiration) Fig. 1
(1) Tilt the victims head back as far as this face looks back. (A pillow may be inserted his neck.)
(2) Push his jaw upward to open his throat wide (to spread his airway).
(3) Pinch the victim’s nostrils and take a deep breath, block his mouth completely with yours
and blow into his mouth strongly. Take a deep breath again and blow into his mouth.
Continue this 10 to 15 times a minutes (blocking his nostrils).
(4) Carefully watch that he has recovered his natural breathing and atop practicing artificial
respiration.
(5) If it is difficult to open the victims mouth, insert a rubber or vinyl tube into one of his
nostrils and blow into it blocking the other nostril and his mouth completely.
(6) When the victim recovers consciousness, he may try to stand up suddenly, but let him lie
calmly and serve him with a cup of hot coffee or tea and keep him warm and quiet. (Never
give him alcoholic drinks.)
Method of mouth-to-mouth respiration by raising head
(1) Raise the victim’s head. Support his
forehead with one of your hand and his
neck with the other hand. 1
When you tilt his head backward, the
victim, in most cases, opens his mouth to
the air. This makes mouth-to mouth
respiration easy.
(2) Cover his mouth as widely as possible with
yours and press your cheek against his nose
2
or, pinch his nostrils with your fingers to
prevent air from leaking. 3
(3) Blow into his lungs. Continue blowing
into his mouth until his breast swells.
Blow into his mouth as quickly as possible
for the first 10 times.
Fig. 1 Mouth-to mouth respiration
- xi -
When both pulse and breathing have stopped
Perform the (Cardiac massage) Fig. 2 and (Mouth-to-mouth respiration) Fig. 1
When no pulse has come not to be felt, his pupils are open and no heartbeat is heard, cardiac arrest
is supposed to have occurred and artificial respiration must be performed.
(1) Place your both hands, one hand on the other, on the lower one third area of his breastbone
and compress his breast with your elbows applying your weight on his breast so that it is
dented about 2cm (Repeat compressing his breast 50 times or so a minutes). (Cardiac
massage)
(2) In case of one rescuer,
Repeat cardiac massages about 15 times and blow into his mouth 2 times quickly, and repeat
this combination.
In case of two rescuers,
One person repeats cardiac massages 15 times while the other person blow into his mouth
twice, and they shall repeat this combination. (Perform the cardiac massage and
mouth-to-mouth respiration)
(3) Examine his pupils and his pulse sometimes. When the both have returned to normal, stop
the artificial respiration, serve him with a cup of hot coffee or tea and keep him warm and
calm while watching him carefully. Commit the victim to a medical specialist depending
on his condition. (Never give him alcoholic drinks.) To let him recover from the mental
shock, it is necessary for persons concerned to understand his situations and the necessary
treatment.
